I just said who did the work and by hand. Meaning free hand. I didnt say by what means and or if a stencil was or was or wasnt used ... Its quite possible he used a curved cut out piece of card board or any other item to aid in getting the same curves, i dont know im not an artist.
I have seen people doing old style sign writing on vans with out using any aids and at the end it looks as clean and neat as a decal or printed so its not unimaginable.
I remember the thread my TE now i will have to re read it..
